Let's get something straight, Gaara does not possess Gold Dust, he had kept a speck in which he used against the Mizukage, it isn't his ability, he doesn't have it end of discussion.
You're insulting Deidara's intelligence, not many ninja can see microscopic nano bombs unless they have Byakugan/Sharingan.
And no it wasn't a fanboy statement, Shukaku Gaara > EMS Sasuke, Shukaku Gaara > MS Itachi, etc. If you want to try and prove me wrong deeming me a fanboy by all means go for it. But I assure you, you will not win.
I don't wanna get into the gold dust debate but let me point out some things.
1. Shukaku doesn't have the relationship with Gaara to break him out of tsukuyomi or any genjutsu Itachi would input onto him. Sure, he can tank his attacks, but what in the literal hell does either gaara have to pierce Yata Mirror, let alone phase it?
2. Shukaku gaara over EMS sasuke, eh? Can shukaku shield tank Kirin? More or so, what does he have against powerful combo attacks with Aoda? It'd just be him sitting there with his ultimate defense, there wouldn't be much to do. Not even yata mirror, what in the world does shukaku gaara have that can get over Susano'o? Incomplete one arm MS Sasuke Susano'o tanked one of gaara's most powerful attacks WITH other attacks with no physical damage.
Kid, shukaku gaara is barely top 25. Quite double guessing yourself. I don't mind gaara fans as I like the character, but "effortlessly into top 10" is one of the most laughable fanboyish statements I have seen not just on here, but in the entire debating community of naruto.
Garra does not possess Gold Dust, he simply kept traces of it from his fight. Presumably for "just in case matters." Deidara wasn't a good match-up for Garra, especially when having yo defend his village and when someone is aware of your abilities and you are not. However, with this being said, Deidara is NO pushover and could defeat some of the strongest characers in the series, so this is no discredit to Garra.
Garra fought multiple susnno clones made Madara, arguably just as durable and powerful. We've seen few chracters "fight" bjuui, it's more like defending for their lives.
Current naruto is high up in the top 10 Shockwave'd and deflected bijuu 1-7 and overcame all of their TBB's. How can you even put any form of gaara in the same list as that?
And the fighting several susano'o clones is just adding on to my claim that War Gaara > Summit Gaara =/= shukaku gaara
